Magnesium Hydroxide (Mg(OH)2) Micron Powder, Purity: 99.9+%, Size: 325 mesh

Description

Magnesium Hydroxide (Mg(OH)₂) Micron Powder

Purity: 99.9+%
Particle Size: 325 mesh

Product Description

Magnesium Hydroxide (Mg(OH)₂) is a white, odorless inorganic compound commonly used in industrial, environmental, and polymer applications. In its micronized powder form, Mg(OH)₂ offers enhanced surface area, uniform dispersion, and efficient thermal reactivity, making it ideal for use in flame-retardant formulations and environmental treatment systems.

This material undergoes endothermic decomposition upon heating, releasing water vapor and forming magnesium oxide (MgO). This reaction effectively absorbs heat, delays ignition, and dilutes flammable gases—making it an excellent fire retardant and smoke suppressant.

Key Properties

• Chemical Formula: Mg(OH)₂

• High Purity: 99.9+%

• Particle Size: 325 mesh

• Endothermic Decomposition: Releases water at ~350–400°C

• Eco-Friendly: Non-toxic, halogen-free alternative to traditional flame retardants

• Chemical Neutralizer: Excellent acid-neutralizing capability

Applications

Micronized Magnesium Hydroxide powder is widely used across industries such as:

• Fire Retardant & Smoke Suppressant:
  Acts as a non-toxic flame retardant in polymers. On thermal decomposition, it releases water and forms a protective barrier of MgO, which suppresses smoke and slows down combustion.

• Plastic and Rubber Industry:
  Can be uniformly dispersed in thermoplastics such as PA (polyamide), PP (polypropylene), ABS, PVC, and various elastomers, enhancing fire resistance without compromising mechanical properties.

• Wastewater Treatment:
  Used as an alkaline neutralizer to treat acidic industrial wastewater, effectively adjusting pH and precipitating heavy metals.

• Environmental Applications:
  As an environmentally benign alternative to halogenated retardants, it supports sustainable product development in electronics, construction, and automotive industries.
